OPTIMIZATION RESEARCH OF JACK-UP STRUCTURE BASED ON ANSYS AND RELIABILITY

摘要

Based on the ANSYS analysis software, parameterized model of jack-up platform is established to optimize the main chord wall thickness of jack-up platform leg structure, pitch, the center distance of the pile legs and other design parameters. Through shape optimization and size optimization of platform structure, suitable bar cross section and shape are chosen to satisfy the limit of deflection and stress under the condition of the least steel structure consumption, thus to reduce the project cost and improve the design level.
